The options of virtualHtml is:

{
  pages: { index: '/index.html', button: '/lib/button/index.html' },
  indexPage: 'button'
}

Looks like it caused by this:

https://github.com/windsonR/vite-plugin-virtual-html/blob/7fe8d8100d1863ce176b96ae1b93f6ba6b88ec6e/src/plugin.ts#L51

maybe you can test this. use res.end to replace res.write in src/plugin.js.
